Abstract
A safety syringe includes a barrel, a plunger, a needle set and a needle sheath. The plunger can be engaged with the needle set after completing an injection with the syringe, and the needle set can be then pulled in into the barrel for storage. Further, the needle set inside the barrel will pose automatically obliquely for avoiding the needle cannula being accidentally exposed exterior to the barrel.
